Which factor contributed MOST to the population changes shown in this table? (8.13B, 8.
A Western lands acquired by the United States had many urban areas.
B Industrialization encouraged people to find work in urban areas.
C Recurring droughts made farming a risky way of earning a living.
D Immigrants typically settled in rural areas of the country.

B

Explanation:

A is incorrect because during this time period, most Western lands were utilized for farming and agriculture, but urban cities.

C is incorrect because droughts weren't very prominent, and even though they were still there, there definitely weren't enough for that to be the main reason for urban immigration.

D is incorrect because most immigrants stayed where the arrived in the US - on the coast (so they didn't settle in rural areas).

Hope this helped!

apart from being against desegregation, governor of georgia eugene talmadge opposed as well to the work progress administration, an ambitious program of the "new deal" created by president franklin d. roosevelt to overcome the great depression after world war i. talmadge disagreed with welfare spending, job training and organized labor. according to his ideas, he thought the government was spending too much money on this, and he wasn't willing to accept a wage higher than georgia's lower average wage. besides, talmadge strongly opposed to the "new deal" as he thought it had communist ideas.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
